What Are The Best Shinsou X Bakugou Fanfiction With Emotional Depth?

Man, everyone's gonna recommend the big, heavy angst fics, and those are good, but sometimes the emotional depth hits harder in a smaller package. 'carry the zero' by bluedynamite is a oneshot that absolutely wrecked me. It's just a simple premise: Bakugo keeps a list of everyone he's ever hurt, and Shinso's name is on it from the Sports Festival. Years later, Shinso finds the list by accident. The whole story is just them talking it out on a rooftop, but the way Bakugo's guilt isn't performative—it's this quiet, festering thing—and Shinso's resentment turning into this weird understanding... it's brutal in the best way. It doesn't need 100k words to make you feel everything. It's all in the dialogue and what's left unsaid. That one stuck with me longer than some of the epic-length series, honestly.

Okay, so you're asking about the really heavy stuff for ShinBaku, the ones that stick with you. I've read a ton, and honestly, a lot of them miss the mark—either it's all smutty rivals-to-lovers with zero buildup, or they make Shinso way too soft, which just feels wrong for him. The gems are the ones that understand both characters are fundamentally lonely, just in different directions. Bakugo's loud about it, Shinso's quiet. The fics that get that dynamic right, where their damage actually complements instead of just colliding, are rare.

'Phantom Pains' by ghostwords on AO3 is probably the best I've ever read. It's a postwar fic where Bakugo has chronic pain from his injuries and Shinso's insomnia is debilitating. They don't even start off liking each other; they're just two insomniacs stuck in the same physical therapy group. The emotional depth comes from how they communicate—or fail to. It's all in the quiet moments, Shinso using his quirk to pull Bakugo out of night terrors, Bakugo forcing him to eat when he's too tired to remember. It feels earned.

There's another one, 'Echo Location,' that plays with the idea of voice. Shinso is losing his quirk due to a side effect of a drug used during the war, and Bakugo, whose entire identity is tied to his loudness, has to learn to communicate without yelling to help him. It's messy. They hurt each other sometimes, say the wrong thing. The author doesn't shy away from that. The comfort isn't fluffy; it's two jagged pieces finding a fit that's not perfect but works. I keep coming back to that one when I want something that feels real, not just wish-fulfillment.

A lot of people rec 'Reverse Engineering' for the clever quirk analysis, but for pure emotional gut-punch, I'd say 'Phantom Pains' is the peak. It ruined me for a week. The ending isn't even traditionally happy, just... peaceful. Which, for them, might be better.
